Q:
Windows 7 - Can't logon in to local admin account - you cannot log on because the logon method you are using is not allowed on this computer

I am having a Windows Server 2003 R2 server having active directory. Users have different OS on their respective client machines (Windows XP, Vista and Windows 7). Out of them one user having Windows 7 tried to change the password, but according to him he
failed to do so due to the complex password requirements. So he canceled and turned off his system. When he came back and tried to login in to the administrator account on his system, he was unable to do so. Following message was displayed: "You cannot log
on because the logon method you are using is not allowed on this computer. Please see your network administrator for more information." Please note that the default administrator account is disabled on this laptop by default.

Other users having Windows 7 client machine are not facing any problem.
